Rijndael对偶密码研究

Research on the Rijndael Dual Ciphers

构建Rijndael平方对偶密码,改变不可约多项式可得到240个对偶密码,分析与其同构的对偶密码,来剖析Rijndael算法,为密码分析提供了新的视角.

Tile Rijndael square dual ciphers are consructed, 240 dual ciphers are generated by modifying the irreducible polynomials. The Rijndael algorithm is deeply analyzed by researching ciphers isomorphic with those dual ones. A new perspective is provided to the cryptogram analysis.
